The seamless scalability is something I see as among the best features Elastic Search offers.
The speed with which Elastic Search is able to search through all of the documents we place into it is quite remarkable, as we search through 65 billion documents in less than a second in most cases, on a constant consistent basis.
I find configuring relevant searches within Elastic Search platform very straightforward. Elastic Search is easily scalable.
The customer support for Elastic Search is quite good.
I advise others looking into using Elastic Search to think about the future of your platform and where you intend it to be in five years, and based on that, which version of Elastic Search best suits the needs of your platform. Additionally, jump into the AI products first as you're in the planning phase so that as you're filling out your data, the AI products and machine learning products can enrich the data real-time early on in the process, which will save you a lot of time later.
The overall performance of the platform, scalability of the platform and other additional features, especially when it comes to AI, really earn the nine.
